[0033] The operating principle of the utility model is as follows:

[0034] like Figures 1 to 4 As shown, a large piece of cardboard is cut by a die-cutting machine into three small pieces of cardboard and transmitted to a diversion mechanism, where a first upper pressing belt 131, a second upper pressing belt 132 and a third upper pressing belt 133 and a corresponding first lower pressing belt 134, a second lower pressing belt 135 and a third lower pressing belt 136 are provided. The corresponding upper pressing belts and lower pressing belts are pressed together to press a small piece of cardboard. At this time, the first transmission motor 101 is started, and the three sleeved transmission wheels 17 drive the three lower pressing belts to rotate, and synchronously drive the pressed together pieces. As the cardboard moves, the corresponding upper pressing belt also rotates. During the movement, since the angles between the axial center line of the first connecting rod 11 and the axial center lines of the first support rod 141 and the second support rod 142 are all 85°, that is, there is a 5° offset angle in the corresponding cardboard moving direction, under the influence of the force of the bonding transmission, the left and right cardboards in the moving direction are spaced apart from the middle cardboard and gradually move outward in an "eight" shape, and the moving direction of the middle cardboard does not change, thereby achieving the purpose of spacing the cardboards apart and diverting the output.

[0035] Subsequently, the sent cardboard moves to the position of the docking mechanism. At this time, the docking mechanism is provided with a first upper conveyor belt 231, a second upper conveyor belt 232 and a third upper conveyor belt 233 and a corresponding first lower conveyor belt 234, a second lower conveyor belt 235 and a third lower conveyor belt 236 at the discharge positions of the three cardboards. Similarly, the corresponding upper conveyor belts and lower conveyor belts are pressed against the cardboards at the corresponding positions. At this time, the second transmission motor 201 is started, and the three lower conveyor belts are driven to rotate by the three sleeved driving wheels 28, and the pressed cardboards are driven to move synchronously, and the corresponding upper conveyor belts are also rotated accordingly, and the three diverted cardboards are redirected and sent out to achieve the purpose of their respective collection. Since the distances between the three cardboards have been pulled apart, the collection between them no longer interferes with each other.

[0036] Finally, during inspection and maintenance, if necessary, start the second power motor 30 again to drive the transmission rod 31 and the transmission tooth 32 to rotate synchronously, and drive the meshing tooth plate 34 to move upward, that is, synchronously drive the support rod 33 connected to the tooth plate 34 to move upward, and make the non-hinge end of the base plate 20 flip upward, and the three upper conveyor belts and the lower conveyor belt connected to the support frame 21 also flip upward synchronously, so as to facilitate the operator to check and move around. After the inspection is completed, start the second power motor 30 again to drive the three upper conveyor belts and the lower conveyor belt to rotate downward to the use position.

[0037] It should be noted that, since the cardboard moves in the horizontal direction, the moving direction of the belt drive will not change without the action of external force. When the spacing needs to be increased, it is only necessary to adjust the spacing of the transmission position, that is, start the first power motor 10 to drive the first connecting rod 11 to rotate, and the screwed first connecting sleeve 151 and the second connecting sleeve 152 move in opposite directions at the same time, and the spacing between the first support rod 141 and the second support rod 142 increases; when in use, the edges of the left and right cardboards first contact the upper and lower pressing belts. Since there is an angle deviation of 5° between the upper pressing belt and the lower pressing belt in the moving direction (such as Figure 2 In the state shown in the figure, the force of the bonding transmission is in a unilateral state. In the adaptive state of force balance, the center position of the cardboard gradually deviates from the axial center of the upward pressure belt. Relatively, the offset distance of the cardboard removal end increases, that is, the distance between the left and right cardboards is increased; correspondingly, the guide rod 162 extends into the groove so that the support plate 16 can move on the guide rod 162. When the position of the upper pressure belt is adjusted, the support plate 16 at the corresponding position is also moved, so that the upper and lower pressure belts at the corresponding positions are bonded to the transmission cardboard. In order to avoid movement and deviation, two guide rods 162 are set, and correspondingly, two sliders 161 are set for quick adjustment and movement.

[0038] Similarly, at the position of the docking mechanism, in order to stabilize the output direction of each of the three cardboards, two upper conveyor belts and two lower conveyor belts are set at each corresponding position. When the spacing is adjusted at the position of the diversion mechanism, the positions of the upper conveyor belt and the lower conveyor belt must also be adjusted accordingly. It is only necessary to push the linear bearing 27 at the corresponding position to move on the connecting rod 211, thereby driving the corresponding lower conveyor belt to move. When the upper and lower conveyor belts overlap and fit together, a latch 261 is provided in the corresponding positioning hole 26, and the bent section 262 is placed in the limiting groove 241, and the inner side wall of the blocking rod 263 is abutted against the outer side wall of one side of the support plate 24 for limiting, and the outer side wall of the corresponding side of the sleeve 25 is fitted with the outer side wall of the latch 261, which means that it is adjusted into place.

[0039] The number of the upper and lower pressure belts and the upper and lower transmission belts in this embodiment should be set according to the actual usage status, and this embodiment is not unique.
